I would stay with the name brands. Buy the least expensive model but go with Leatherman, Vic, Gerber or SOG.
I have an original Leathermen Supertool and it is worth every penny. I don't EDC it or even use it much but it does come in handy.
A lot of the cheaper brands are of much lower quality. I saw one the other day that BCB sells; it was so dull I ran the edge of the blade across my palm. It was way too dull to even leave a scratch.
